This nonprovisional application claims priority to U.S. Provisional Patent Application Ser. No. 61/904,635, filed on Nov. 15, 2013, which is hereby incorporated by reference in its entirety.

FIELD

The field of this disclosure relates generally to collapsible chairs, and more particularly, to collapsible chairs having a removable, cushioned seat pad.

BACKGROUND

Known collapsible chairs are popular because they can be readily folded, transported, and stored. Such features enable collapsible chairs to be transported and used during outdoor recreational activities, such as sporting events, concerts, etc. Spectators at such events often use collapsible chairs while engaging in social activities in a venue's parking areas (such as “tailgating”) before and/or after the event. At least some known collapsible chairs include a frame that is selectively moveable between a collapsed or folded configuration when the chair is not in use and an extended configuration during use. Such collapsible chairs are significantly large when in use (i.e., in its extended configuration) as compared to its collapsed configuration. Many venues do not allow spectators to bring in such collapsible chairs because seating is often provided.

Bleacher-type seating is provided at many venues for spectators of sporting events, concerts, etc. While bleacher-type seating can provide simple, convenient seating for a large number of spectators, it does not generally provide comfortable seating. To improve the comfort of bleacher-type seating, spectators sometimes bring their own portable seats or cushions. A spectator who chooses to participate in tailgating activities and who chooses to use his or her own portable cushion in the venue is required to bring two of their own devices to the event, which requires additional storage room in a vehicle. Therefore, there is a need to provide convenient, portable, and comfortable seating for the spectator both inside and outside of the venue.

SUMMARY

In one aspect, a collapsible chair generally comprises a frame selectively moveable between a collapsed configuration of the chair and an extended configuration of the chair. The chair also includes a seat that is coupled to the frame. The seat includes a first material layer and a second material layer, the first layer and the second layer cooperatively defining a seat pocket. A seat pad is selectively moveable between a stored configuration, wherein the seat pad is located in the seat pocket, and a portable configuration, wherein the seat pad is removed from the seat pocket and usable as a portable seat pad.

In another aspect, a method of using a collapsible chair having a removable seat pad generally comprises moving a frame from a collapsed configuration of the chair to an extended configuration of the chair.

As seen in FIGS. 1-3, the collapsible chair 10 includes a frame 12 selectively moveable between an extended, use configuration 14, as seen in FIG. 1, and a collapsed, stored configuration 16, as seen in FIG. 2. In the extended configuration 14, the frame 12 extends a width 18. The frame 12 may be folded, for example, to form the collapsed configuration 16 such that the width 18 of the frame 12 is substantially decreased and the collapsible chair 10 may be stored in, for example, a closet or a trunk of a car. The frame 12 can be moved from the collapsed configuration 16 to the extended configuration 14 wherein the width 18 of the frame 12 is substantially increased and a user may sit on the collapsible chair 10. The frame 12 may be made from plastic, metal (e.g., steel, aluminum, etc.), or any suitable material that enables the collapsible chair 10 to function as described herein.

In the exemplary embodiment, the frame 12 includes a plurality of connecting structures 20 coupled between a pair of outer frames 22. A seat 24, a back support 26, and a foot support 28 are coupled to the frame 12. More specifically, the back support 26 and the foot support 28 are coupled between the outer frames 22, and the seat 24 is coupled between the two connecting structures 20. Accordingly, during use of the collapsible chair 10, the user may be seated on the seat 24, may position his or her back against the back support 26, and may position his or her feet on the foot support 28. In the exemplary embodiment, the seat 24 and the back support 26 are formed as separate pieces. It is understood, however, that the seat 24 and the back support 26 may be formed as a single-piece.

In the illustrated embodiment, each outer frame 22 is generally rectangular in shape and comprises a pair of horizontal members, i.e., a lower horizontal member 30 and an upper horizontal member 32, and a pair of vertical members, i.e., a front vertical member 34 and a rear vertical member 36. The rear vertical member 36 includes an upward extending portion 38 that extends beyond the upper horizontal member 32. Each of the front vertical members 34 includes a lower foot peg 46 extending forward, transverse to the vertical member 34.

The first material layer 50 and the second material layer 52 may be joined together at a plurality of seams 58 parallel to and located proximate the horizontal members 42 of the connecting structures 20, for example, by sewing, adhesive bonding, heat welding, or other bonding technique along the length of the seams 58. In one suitable embodiment, the seat 24 can be made from a single piece of material such that the second material layer 52 is folded approximately 180 degrees along a front edge 56 of the seat 24 so the second material layer 52 is in a face-to-face relationship with the first material layer 50. In another suitable embodiment, the seat 24 may be made from separate pieces of material, wherein the first material layer 50 and the second material layer 52 are joined together at the front edge 56, for example, by sewing, adhesive bonding, heat welding, or other bonding technique along the length of the front edge 56. In the illustrated embodiment, the second material layer 52 also includes a free edge 60, i.e., the free edge 60 is not coupled to the first material layer 50, thus forming a substantially rectangular-shaped pocket 54 in the seat 24.

In the illustrated embodiment, a seat pad 70 (FIGS. 4 and 5) is substantially rectangular in shape and configured to be inserted in the pocket 54 of the seat 24 to provide a padded seat for the collapsible chair 10. The pocket 54 of the seat 24 is configured to receive and store the seat pad 70 therein. Specifically, the pocket 54 is configured to hold the seat pad 70 within the pocket by the tension of the seat 24, i.e., the illustrated pocket does not include a closure device. It is understood, however, that the pocket 54 can include a closure device configured to selectively open and close the pocket, such as, without limitation, a zipper, a drawstring, a hook-and-loop fastener, or any suitable closure device that enables the pocket 54 to be selectively opened and closed.

The seat pad 70 is also configured to be used separate from the collapsible chair 10 to provide a portable, comfortable seat for the user. With reference to FIG. 5, the seat pad 70 includes a covering 72 and a filling material 74. The covering 72 comprises a plurality of panels, including a lower panel 76, an upper panel 78, a pocket panel 80 overlying in face-to-face relationship the upper panel 78, and four side panels 82. The panels 76, 78, 80, 82 may be joined together, for example, by sewing, adhesive bonding, heat welding, or other suitable bonding technique. The panels 76, 78, 80, 82 may be made from a wide selection of materials, such as, but not limited to, synthetic materials (for example, polyester or polypropylene materials), natural materials (for example, wood or cotton materials), and/or a combination of natural and synthetic materials. In one suitable embodiment, the panels 76, 78, 80, 82 are made from a durable waterproof material.

In the illustrated embodiment, the filling material 74 is fully enclosed within the covering 72 by the lower panel 76, the upper panel 78, and the side panels 82. The side panels 82 are connected to the upper panel 78 and the lower panel 76, and cooperatively extend around the periphery of the upper panel 78 and the lower panel 76. In one suitable embodiment, the filling material 74 comprises foam for providing cushioning to the user. Examples of suitable foam include a closed-cell polyolefin foam, a polyethylene foam, a low-resilience polyurethane foam, a foam with a negative Poisson's ratio, and other similar foams.
